Create a mysql user

[root@Master home]# useradd mysql[root@Master data]# echo 'mysql'|passwd --stdin mysql

Change your mysql password.

Passwd: All authentication tokens have been successfully updated.

Reasons for creating a mysql user

If you do not need mysql, an error occurs. You have tried it many times and added the mysql user to install it successfully.

* Of course, many users have already been created to complete routine operations. If you do not create a mysql user, modify the mysqld_safe file in the mysql/bin directory. // The test is successful.

Procedure:

[Root @ Master bin] # vim mysqld_safeuser = 'mysql' change to user = 'hadoop '// the subsequent steps are basically the same. * [root @ Slave1 data] # service mysql startstartstarting mySQL ...... ERROR! The server quit without updating PID file (/home/hadoop/ruanJian/mysql/data/Slave1.Hadoop. pid ). [root @ Master data] # vim Slave1.Hadoop. err // view log file 160830 15:56:44 mysqld_safe Starting mysqld daemon with databases from/home/hadoop/ruanJian/mysql/data2016-08-30 15:56:49 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. please use -- explicit_defaults_for_timestamp server option (see docu Mentation for more details). 15:56:49 1990 [ERROR] Fatal error: Can't change to run as user 'mysql'; Please check that the user exists! 15:56:49 1990 [ERROR] Aborting2016-08-30 15:56:49 1990 [Note] Binlog end2016-08-30 15:56:49 1990 [Note]/home/hadoop/ruanJian/mysql/bin/mysqld: shutdown complete160830 15:56:49 mysqld_safe mysqld from pid file/home/hadoop/ruanJian/mysql/data/Slave1.Hadoop. pid ended

Create and decompress the data directory under the mysql user

[Root @ Master data] # tar-zxvf mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz [root @ Master data] # mv mysql-5.6.12-linux-glibc2.5-x86_64 mysql // rename

Set permissions

[root@Master data]# chown -R mysql:mysql mysql

Switch the user to the mysql/scripts directory.

[root@Master data]# su mysql[mysql@Master data]$ cd mysql/scripts/[mysql@Master scripts]$

Installation (the directory is set according to the mysql decompression directory)

[mysql@Master scripts]$ ./mysql_install_db --user=mysql --basedir=/home/mysql/data/mysql --datadir=/home/mysql/data/mysql/data
